How To Prevent The Failure Of Transformer Operation?

Oil Immersed Transformer Manufacturer shares that operators should be familiar with the causes of transformer faults so that they can take timely treatment and preventive measures. Transformer is an extremely important electrical equipment in the transmission and distribution system. Compared with other electrical equipment, its failure rate is very low. But once the failure occurs, it will bring serious losses to industrial and agricultural production. In order to make the electrical operation and maintenance personnel can do regular inspection and maintenance work, eliminate equipment defects, to ensure the safe operation of transformers, transformers put into operation, the common fault is: insulation oil deterioration, lightning, lead insulation fault, casing damage, tap switch fault and other fault reasons. Let us understand the transformer in detail after the operation are prone to what fault problems?

Transformer fault reasons and preventive measures:

Transformer is an extremely important electrical equipment in the transmission and distribution system. Compared with other electrical equipment, its failure rate is very low. But once the failure occurs, it will bring serious losses to industrial and agricultural production. In order to make the electrical operation and maintenance personnel can do regular inspection and maintenance work, eliminate equipment defects, to ensure the safe operation of transformers, based on many years of transformer operation, maintenance experience analysis of the main causes of failure and preventive measures.

1. Insulation oil deterioration

Insulating oil may come into contact with air during operation and gradually absorb moisture from the air to reduce the insulating performance. Insulating oil also could absorb, dissolved air in great quantities, because the oil often run at higher temperatures, oil contact with the oxygen in the air, produce various oxides, and the oxide are acidic, and easy to use copper, aluminum, iron, insulation materials from corrosion, to increase the dielectric loss of oil, the oil degradation, the transformer internal flashover, puncture accidents.
